@mxcl do you know what is up here? |
|
I removed this feature as it occurred to me it underwent no real design or consideration and was merged before we even had testing support. It would be enough to discuss it here. |

One possible solution is to enhance Package.swift to support conditional dependencies. Something like: .package(url: "https://...", from: "1.0.0", when: .testing),
.package(url: "https://...", from: "2.0.0", when: .os(.linux),We need to design and discuss this feature on Swift forums, possibly as part of build settings which is related to this JIRA. |

Issue Description:
When
swift-testwas merged, fetching and building of test-only dependencies was removed. This appears to be a known issue, as the related tests were disabled: https://github.com/apple/swift-package-manager/blob/c3e97ac83bd1552f4312030a0004fab8b9134b32/Tests/Functional/TestMiscellaneous.swift#L75.Expected: Test-only dependencies should be downloaded and built, and be able to import XCTest.
Actual: Test-only dependencies are ignored, although they can be added to the standard list of dependencies as a workaround. However, when building a building a test dependency, packages are unable to be linked against XCTest.
